TRA'VEB, OI PROVIDENCE, RHODE ISLAND,ASBIGNOB '10 FRANKLIN PROCESS COMPANY, 01' PROVIDENCE, RHODE ISLAND, ACORPORATION OD! ISLAND SPOOL, BEAM, 03. THE LIKE Application filedFebruary 15, 1929. Serial No. 340,202.

This invention relates to improvements in the construction of s ools,beams, reels or the like for use in trans er processes or for dyein andsimilarly treating yarn, thread and ot er textile materials.

One object of the invention is to provide a construction for a spool,beam or the like which will be light in weight yet strong and durable towithstand rough handling in the processes in which it is used.

Another object of the invention is to proride a construction for aspool, beam or the like in which the heads are securely attached to thebarrel to insure against their becoming loose from the pressure of thematerial wound thereon or from the strains imposed in use.

Another object of the invention is to provide a construction for aspool, beam or the lilre which may be manufactured at low cost 0 renderit economical for use in large numers.

Further objects of the improvement are set forth in the followingspecification which describes a preferred form of construction of i theinvention as illustrated by the accompanying drawings. In the drawings:

Fig. 1 is a longitudinal view of the improved spool or beam;

Fig. 2 is an end view of the same; and

Fig. 3 is an enlarged sectional view of the spool taken on line 33 ofFig. 2, showing the method of attaching the heads to the barrel.

The embodiment of the invention herein shown is in the form of a jack-spool or beam and comprises a hollow barrel 2, flange-like heads 3,and bearing-hubs 4. The tubular barrel 2 may be made of any suitablelightweight, durable material such as sheet-metal or fiber, and whenintended for use in dyein the walls of the barrel 2 are perforated withcircumferentially arranged apertures to allow the egress of fluidsforced through its central opening. The ends of the barrel 2 are reducedslightly in diameter for a short distance to form shoulders 5 whichfunction for a urpose as later explained.

he heads 3 may be made in one piece, but

as here shown they comprise two parts, a relatively thin disk 6 and aseparate annular flange 7. The disks 6 may be cut or stamped fromsheet-metal and for certain uses holes 16 are drilled or punched thereinadjacent their peripheries to provide means for holding the end of theyarn, thread or other material wound on the. spool. The annular flanges7 may be cast, or punched from heavier stock, and are tapered 1ncross-section toward their peripheries. Radially-dis osed holes aredrilled through the flanges and threaded to receive studs for a purposeto be later explained. The disks 6 and flanges 7 are permanently securedtogether by rivets 8 and the resultant structure is axially bored toform a tapered hole 9 which adapts the head 3 to be mounted on thereduced end of the barrel 2 with its side abutting the shoulder 5,previously mentioned.

The hubs 4 are constructed with an axial bore of slightly less diameterthan the opening in the barrel 2 and are formed with circumferentialflanges 11 provided with countersunk holes 12 for receiving screws 14which secure them against the outer faces of the flanges 7. The inwardlyprojecting portions of the hubs are of tapered or frustroconical sectionat 15 to correspond to the taper of the axial holes 9 in the heads 3.

In assembling the parts of the spool, the

heads 3 are placed on the reduced ends of the barrel 2 against theshoulders 5. The tapered portions 15 of the hubs 4 are then forced intothe ends of the barrel 2 and the flanges 11 secured fast to the heads 3by means of the screws 14. As the hubs 4 are forced into the bore of thebarrel 2 their tapered portions act in the manner of a wedge to expandthe ends of the barrel outwardly to bind them in the tapered holes ofthe heads 3. When the screws 14 are tightened a firm, secure joint iseffected between the parts to rigidly and fixedly hold the flanges orheads in place.

By the novel arrangement of the parts as above described, a. rigid andserviceable spool or beam is provided which is practically proof againstdamage, breakage or distortion in use or from rough handling.Furthermore, the heads are so mounted on the barrel and reinforced bythe end hubs and flanges that they will remain in perpendicular relationto the axis of the barrel and parallel with each other under thepressure of the yarn mass wound on the barrel. The layers or coils ofyarn are thus prevented from becom- 5 ing displaced'or disarranged asthe mass is built up on the spool. It will also be observed from theforegoing that the improved jackspool or beam is extremely simple inconstruction, so that it may be manufactured at 10 relatively low cost.

While I have herein shown and described a preferred embodiment of theinvention, various modifications may be made in the structure andarrangement of the parts of the device without departing from the spiritand scope of the invention. Therefore, without limiting myself in thisrespect, I claim:

1. A spool or beam comprising a tubular barrel, relatively thin diskshaving axial openin s fitted to the ends of the barrel, an-

nular anges of greater'thickness than the disks overlying the outerfaces of the latter and having tapered bores for receiving the ends ofthe barrel, hub-members having annular tapered portions inserted intothe ends of the barrel to wedge the terminal portions thereof outwardlyinto binding engagement with the tapered bores in the flanges, saidhub-members having peripheral flanges abuttin the faces of the annularflanges, and means or fastening the flanges together and to the disks tofixedly secure all the parts in permanent relationship.

2. A spool or beam comprising a tubular 35 barrel having its peripheryreduced in diameter at its ends to provide annular shoulders, diskshaving axial openin s fitted to the reduced end portions of the barrelin abutting relation to the shoulders thereon, annular flanges overlyingthe outer faces of the disks and provided with tapered bores forreceiving t e ends of the barrel, hub-members having tapered portionsinserted into the ends of the barrel to wedge the reduced portions 45thereof into binding engagement with the bores in the flanges, saidhub-members having peripheral flanges abutting the faces of the annularflanges, and means connecting the flanges to effect a permanent joinderof the parts.

In testimony whereof I hereunto aflix my signature.
